Across 43 used Hyundai Sonatas we inspected, this model scores about average — average condition 61/100 vs 61 for all cars we check.

Not owner surveys, not warranty statistics, not forum lore: what we actually found.

Straight from recent Hyundai Sonata reports

2014 Hyundai Sonata · 113k mi — flagged: smoothness, oil leaks, dirty or low engine oil. Inspected Jun 23.

The bottom line

These Sonatas mostly land in the middle of the pack, but the real story is deferred engine care: oil leaks hit 60 percent of them, often joined by out-of-range fuel trim or dirty oil. That pattern plus tired tires and worn suspension joints points to cars that look fine until you dig. On any example you’re considering, start under the hood for fresh seepage and oil condition, then check tread depth and joint play before anything else. Light issues are bargaining chips; active leaks or multiple engine flags mean walk—cleaner ones do turn up.
